ELECTRIC LOCOMOTIVE.

Specification of Letters Patent.

Application filed April 30, 1909. Serial No. 498,093.

1' and State of New York, have invented certain new and usefulImprovements in Electric Locomotives, of WlllCll the following is aspecification.

My invention relates to electric locomotives and particularly totwo-truck locomotives.-

The object of my invention is to provide in a two-truck locomotive anarran ment of driving motors such that the weight of the same shall beconcentrated as near the middle of the locomotive as ossible in order todecrease the moment 0 inertia of the locomotive about a vertical axisthrough its center, thereby to relieve the lateral hammer blowsof theleading wheels of the locomotive upon the rails due to nosing action. -I

In carrying out the above mentioned object of m invention, I drive thewheels of each truc of a two-truck locomotive by a motor arranged incooperative relation to the pair of wheels in each truck which isnearest. the other truck, driving connections being provided betweenthese wheels and the other wheels of that truck. By this arra ement themotors are located near the midd fi of the locomotive and the ends ofthe trucks nearest the ends of the locomotive mag be made light.

eferring to the drawing, Figure 1 is a side elevation of the trucks of atwo-truck locomotive, a portion of the frame ofone truck'bei'ng brokenaway and the motor on that truck being shown 1n crosssection;-and Fig. 2is a plan of the trucks shown in Fig.

1, the body frame of the cab of the locomotive bein shown in outline indash lines. 'Beferrmgto Figs. land 2, the trucks A and B are shown aseach provided with two.

pairs of wheels, the axles of which are mounted for limited verticalmovement in truck frames 11 and 12 of similar design. 'The journal boxesfor these axles and the mannerin which they are mounted in the truckframes need not be described here since they may be of any well knownstyle ,and form no part of my invention. .Each l truck frame issupportedupon the journal boxes of itsaxles by spring systemsof susiili pensionhereinafter described. trucks- 'ne arest the other two I, an 'drivin areconnected by a lead .ng-connection 13 of any suitable and well-k1 LOWIIform, this connection servin as a hing ed joint between the trucksthrong which the tractive efiort of one truck is transmittec to theother, it being understood that in the particular loco Patent ed Nov.14, 1911.

motive shown the draw bars are mounted upon'the truck frames. The truckA is connected to the body frame of the cab by a lvotal connection 14,of any well-known orm, and the truck B is connected to the armaturesurrounds the wheel axle, the field structure ofeach motor being builtinto and forming a part of the truck frame.- The manner in which thearmatures of these motors are supported a1 amid the wheel axles will befully described and claimed in a divisional application. The wheel axlesof each truck are geared t; gether by crank pins and connecting rod co:mections, as clearly shown'in Figs. 1 and 2, the crank pins being shownat 21 and the c( nnecting rods at 22.- The cranks on each wheel axle atopposite sides of the truck are, c 15 course, set at right an les inorder that'tha connecting rods on bot sides of the truck maynever beupon dead center at the same time. The frame of the truck A is supportelupon its four journal boxes by sprin 25, links 26 and equalizing levers27 duplicated on both sides of the truck and arranged as shown int-hedrawing. The frame of the truck B is supported upon its journal boxesthrough springs 35,

links 36 and once uilizing lever 37 arranged as shown. his system ofsuspension' for the motor fra: nes is described and claimed in adivisional application.

What I claim as new and desire to secure by Letters Patent of ti eUnited States, is,

1. In an electric lot emotive, two trucks. each having a" pluralit; ofpairs of wheels, one motor mounted on each of said trucks adjacent toand driving the air of wheels connections between the ax .es of eachtruc and a leading connection be meen said and driving the pair ofwheels nearest the 1 middle of the locomotive, crank and connect {ingrod driving connections between the Wheels of each truck, and a. leadingconnection between said trucks.

In Witness whereof, I have hereunto set my hand this 28th day of April,1909.
